mit tube mi Y`hmm by 'wml 13min-lles a belly l inwardly, as clearly shown by Fig. 6. The bottom plate 24 has a flange 27 which con` nected to the parts 25 and 26 of the upper wall by radial ribs or partitions 3U, said bottom plate being also formed with a chamber intersected at intervals or divided by the said radial ribs or partitions 3'0, the cham ber 29 being fully open between the ribs or partitions '30 to the interior of the draft tube a short distance above the draft tube flange 282, as clearly shown in Fig. 1. The inner wall 31 of the bottom plate 24 is unbroken by inward projections and is inclined inwardly in the same plane-as the inner surface of the draft tube 28 so as to provide for an. unobstructed clearance and outflow of the water after engaging ,the blades 6 of the 'runner through the said draft tube. The outer side wall 32vof the bottom plate or frame 24 is formed with a plurality of inlet ports or openings 33 between the ribs or partitions 30. The annular plates or ring frames 13 and 24 are both engaged by an outer component or inclosingannular frame 34, shown in inverted position by Fig. 3, and directly engaging the scroll 35, as shown by Fig. 1, and provided with a plurality of inlet openings 36 intersected by diffusers 37. The flange 23 of the top plate or frame 13 extends over a portion of the top of the intermediate inclosure 34, see Figs. 1, 4 and 7, and is .secured to the inclosure by suitable bolts, the top portion of the inclosure being formed with an outwardly projecting peripheral flange 37' which in turn is secured by suitable bolts to the upper inner portion of the scroll. The lower part of the intermediate inclosing frame or component 34 is secured to an offset 38 extending. from the inner portion of the scroll, or the same may be a part of the base support for the turbine. It will be seen that the openings 3G gradually converge inwardly and coincide with the bottom and top portions respectively of the plates or frames 13 and 24, and the' gates 41 are so shaped as to regularly continue the' openings at a gradual downward angle of inclination in a curved plane without obstruction, and, moreover, the connecting webs 39 of the runner blades 6 move in an annular seat 40 in the upper inner portion of the plate or frame 24 Hush with the adjacent portion of the extension 2G and the top of the said frame or plate 24. It will therefore be seen that the space between the bottom of the frame or plate 13 and the top of the frame or plate 24 forms a part of the passage for the water coming in from the scroll through the openings or main inlets 3G between tl ditfusers 37, the water striking the blades" of the runner to the best advantage :mdfavithout obstruction, so that the greatest possible ellciency of the water may be obtained in its action on the runner.

The difflisers 37 are disposed at an angle or are tangential so as to cause the water to have an angular direction relatively to the gates 41, said gates being located between the planes of the bottom of the top frame or plate 13 and the top of the bottom plate or frame 24, and having shafts 42 projecting' able pins or studs 44 mounted in any preferred manner in an outstanding flange 45 at the base of the shifting ring 15 and whereby all of the gates may be uniformly opened and closed or moved to regulate the inflow of the water to the runner from the scroll. At the points where the shafts 42 extend through the bottom of the top plate or frame 13 and the top of the bottom plate or frame 24, water-tight bearings or packings will beAintroduced to prevent leakage at Y said points of the water into the chambers 17 and 29, but the upper and lower portions of the shafts 42 are water-lubricated and ass through tubes 46 which are fixed at t eir upper and lower ends and have 'intermedlate slots or openings 47 exposing the in? termediate portions of the upper and lower parts of the shafts to the water'in the chambers 17 and 29, with obvious advantages in the movement of the said shafts( The shafts 42 are so mounted and connected to the mechanism with which they coperate that vibrations of the gates will be absorbed a '1d therefore will not atfectfthe power transmission mechanism or the mechanism which the turbine is adapted to actuate.

At the upper and lower portions of the .inner side of the intermediate inclosing frame or component 34, annular channels 48 and 49 are formed and divided by partitions 50 and 51, the said channels respectively standing opposite the outlet openings 22 of the top plate or frame 13 and the luie openings or ports 33 of the bottom plate or frame 24. The annular channels 48 and 49 are also located above and below the diffusers 37, and as clearly shown by Fig. 7 the sa id ditfusers are formed hollow, as at 51, and have their upper and lowerportions respectively communicating with the lower portion of the channel 48 and the upper portion vof the channel 49. In other words, the diti'users serve asducts for setting up communication between the upper divided chamher 17 and the low'er divided chamber 29 of the top plate 13 and bottom plate 24 in addition to their function of diffusing the ings therethrough between the channels with tubular diffusers and vates between the latter to control the suppf of water to the runner from the water supplying means,

the tubular diflusers communicating with the channels of the intermediate frameV mediate frame having o enings therethrough between the channe s with tubular diifusers therein, gates coperating with and between the di'users and the said opposed frames to control the supply of water to the runner from the supply means, the gates having shafts projecting therefrom extending through the chambered structure, and tubes fixed in the chambered structure and through which the gate shafts movabl'y extend, said tubes having openings therein to water-lubricate the gate shafts.

v 5. A turbine installation comprising a casing, a runner and shaft therefor, a draft -tube for egress of the water' from the run- `ner, water supply means'forthe runner, the casing embodying a chambered structure around the point of engagement of the shaft with the runner and also adjacent to the point of engagement of the periphery of the runner with the casing for receiving accumulated water, the water being thrown outwardly from the shaft into the outer portion of the chamber, and means for automatically relieving the chamber of 'water accumulated therein.

6. A turbine installation comprising a casing, a runner and shaft therefor, a draft tube, water supply means for the runner, the casing embodying a chambered structure around the point of engagement of the the casing also supply means for the runner,

7. A turbine installation `comprising a' casing, a runner,

a draft tube, water supply means for ie runner. said casing embodying a chamberedi structure at one end of the runner, and drain devices adjacent to the runner and between the same yand the slipply means and in communication wit the draft tube for automatically relieving the said chambered strlcture and the adjacent portion of the runner of accumulated water.

8. A turbine installation comprising a casing, a runner therein, a draft tube, water' the casing embodylng a chambered structure llocated at one end of the runner and extending outwardly beyond said runner to receive water4 accumulating adjacent to the runner, the Waterbeing centrifugally thrown outwardly in the chambered structure by the runner, and drain devices within the casing between the outer portion of the chambered structure and the draft tube for automatically relieving said chambered structure of accumulated water.

9. A turbine installation comprising a casinlg, ya runner therein, a draft tube, water supp means for the runner, the casing having a chambered structure therein extending outwardly beyond the periphery of and adjacent to the runner, and drain de vices within the casing between the outer portion of the chambered structure and the draft tube for automatically relieving the chambered structure of accumulated water.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
